I'm not sure it's the bypass. It'd have to be pretty cold for it to really effect the TB. 50-55 isn't even freezing. In some parts of the country that's swimming weather.

I'd wait a few days to see if it comes back. Without knowing much...I'd say maybe some bad gas?

Pretty strange though.

yea...I guess it's always best to start simple. I'd still take it to the deal though...just in case.

That really sucks. Did you check you MAF sensor to make sure it and its seal were ok? Maybe sucking in air behind it? Just guessing. That might make you run rich...more air coming in than the MAF sees?

I'd be interested to see if the MAFci box was messed up.
